Research Products 6829 Rectangular Zone Damper with Motor

Product Description

The RESEARCH PRODUCTS 6829 is a rectangular zone damper with an integrated synchronous motor, designed for use in residential and light commercial HVAC zoning systems. The damper operates on a power-closed, spring-open principle, meaning it closes under motor power and returns to the open position when power is removed. The motor runs at 24 VAC at 60 Hz, drawing 6 watts and 12 VA. Built from galvanized steel with bottom mounting, the 6829 measures 23-7/8 inches wide by 9.813 inches tall and carries a pressure rating of 1 in-WC. Licensed HVAC technicians install this damper as part of a multi-zone forced-air system to control airflow to individual zones.

The 6829 is suited for rectangular duct runs in residential forced-air systems and light commercial applications requiring airflow zoning. The galvanized steel construction handles the temperature and humidity conditions typical of supply and return duct environments. The flexible link design used in residential sizes absorbs minor duct movement without binding the blade assembly. The spring-open fail-safe action keeps airflow available to connected zones if the control signal or power is interrupted, which is an important operational consideration during controller or transformer failures in multi-zone setups.

Key Features

• Power-closed, spring-open operation provides fail-safe airflow on power loss
• Synchronous motor rated at 24 VAC, 60 Hz, 6 W, 12 VA for compatibility with standard zone control boards
• Galvanized steel construction for corrosion resistance in duct environments
• Bottom mounting configuration for straightforward duct installation
• 1 in-WC pressure rating suitable for residential and light commercial duct static pressures
• Rectangular shape fits standard rectangular duct openings at 23-7/8 inches wide by 9.813 inches tall

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct zoning applications in residential and light commercial forced-air HVAC systems requiring a 24 VAC synchronous motor-driven damper.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and low-voltage control wiring. Disconnect power to the air handler and zone control panel before installing or replacing a zone damper. Confirm the duct opening dimensions match the damper blade size before securing the unit, and verify the control board output is rated for the motor VA draw. Consult applicable mechanical codes for duct penetration and fastener requirements.
